15 صفحه اولGalaxy Pairwise Velocity Distributions on Non-linear Scales
The redshift-space correlation function ξs for projected galaxy separations <∼ 1h Mpc can be expressed as the convolution of the real-space correlation function with the galaxy pairwise velocity distribution function (PVDF). An exponential PVDF yields the best fit to the ξs measured from galaxy samples of different redshift surveys. We show that this exponential PVDF is not merely a fitting fun...
متن کاملnon-linear study of various slit shear walls in steel structures
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
15 صفحه اولNon-linear Approximations to Gravitational Instability: a Comparison in the Quasi-linear Regime
We compare different nonlinear approximations to gravitational clustering in the weakly nonlinear regime, using as a comparative statistic the evolution of non-Gaussianity which can be characterised by a set of numbers Sp describing connected moments of the density field at the lowest order in 〈δ2〉: 〈δ〉c ≃ Sn〈δ〉. Generalizing earlier work by Bernardeau (1992) we develop an ansatz to evaluate al...
متن کاملLarge-Scale Structure Formation in the Quasi-linear Regime
The understanding of the large-scale structure formation requires the resolution of coupled nonlinear equations describing the cosmic density and velocity fields. This is a complicated problem that, for the last decade, has been essentially addressed with N-body simulations. There is however a regime, the so-called quasi-linear regime, for which the relative density fluctuations are on average ...
